*
* General remark about SetupDi functions
*
* Windows NT and Windows 98 implement many of the SetupDi query
* functions differently if you are querying for the buffer size.
*
* Windows 98 returns FALSE, and GetLastError() returns
* ERROR_INSUFFICIENT_BUFFER.
*
* Windows NT returns TRUE.
*
* So all calls to SetupDi functions that do querying for the buffer
* size should be wrapped with BUFFERQUERY_SUCCEEDED.

// Create a Hardware page for the specified GUID.
//
// Parameters:
//
// hwndParent - The dummy frame window created by the caller
// pguid - The setup device class GUID we will manage
//
// Returns:
//
// HWND of the created subdialog.
//
// Usage:
//
// When your control panel applet needs a Hardware page, create
// a blank dialog template titled "Hardware" and add it to your
// control panel. Set the size of the blank to be the size you
// want the final Hardware Tab page to be.
//
// Your dialog box procedure should go like this:
//
// BOOL HardwareDlgProc(HWND hdlg, UINT uMsg, WPARAM wp, LPARAM lp) {
// switch (uMsg) {
//
// case WM_INITDIALOG:
// // GUID_DEVCLASS_MOUSE is in devguid.h
// hwndHW = DeviceCreateHardwarePage(hdlg, &GUID_DEVCLASS_MOUSE);
// if (hwndHW) {
// // Optional - Set the troubleshooter command line.
// // Do this if you want a Troubleshoot button.
// SetWindowText(hwndHW,
// TEXT("hh.exe mk:@MSITStore:tshoot.chm::/hdw_drives.htm"));
// } else {
// DestroyWindow(hdlg); // catastrophic failure
// }
// return TRUE;
// }
// return FALSE;
// }
